Tailingsfo What are tailings?

Tailings characteristics can vary greatly and are dependent on the ore mineralogy together with the physical and chemical processes used to extract the economic product Ritcey (1989) reported that tailings of the same type may possess different mineralogy and therefore will have different physical and chemical characteristics Get price



In the blast furnace magnetic iron ore (Fe3O4) and haematic iron ore (Fe2O3) are fed along with limestone into a high temperature chamber containing coke Coke is partially oxidized to carbon monoxide which reduces the ores to iron The other product that floats over the molten iron due to its relative lightness is called slag Get price
